GAS-BU RNER.

SPECIEIGATION forming part of Letters Patent No. 515,669, dated February Application filed February 23, 1893. Serial No. 463.389. (No model.)

To aZZ whom t may concern;

Be it known that I, HENRY A. FRY, a citizen of the United States, residing in t-he city and countyof San Francisco and State of Califorma, have mvented an Improved Gas-Bnrner, of which the following is a full speoifioation.

My mvention is an improvement in that Glass of gasbnrners which are espeeially designed and adapted for heating the gas before reachmg the fiame, for the purpose of increasingnts combnstibility and thereby prodncing a higher degree -of illumination.

The details of construotion and combination of parts are hereinafter descrihed and shown 1n aocompanying drawingsin which-- Figure 1 s a central longitndinal section of lny bnrner, normal size. Fig. 2 is a cross section on line ac--x Fig. 1. Fig. 3 is a perspective view of one of the longitndinal seotions of the heat-conductor or inner shell of the bnrner. Fig. 4 is a plan view of one of the perforated gas-heating plates arranged wlthm the bnrner. Fig. 5 is a plan view of one of the wire-gauze disks which are also arranged within the burner.

The pear-shaped body O, of the burner is a thin netal (preferably brass) shell, and, as shown 111 Fig. 1, it is divided transversely, or 1n other words, made of two parts,whieh are su tably Secured together by a gas-tight joint. said body O, is provided With a gas passage B, at the bottom, which is so small or narrow as to hlnder an undue rapidity of flow of gas, so as to allow only such qnantity of gas to pase as can be duly heated and mixed in the chamber of the but-ner, without danger from ezrplosion. The body O, is fnrther provided with a. lining or inner shell G of like form, which serves as a beat-conductor as hereinafter described. This shell is formed in longitudinal seotions (see Fig. 3) which are made of some good heat-oonducting material, such as steel, and of such dimensions as to fit loosely within the body O,in order to allow a certain due degree of expansion by heat. Each section of the host-conductor G, has a series of apertures or soekets N, as shown best in h'ig. 3, which holes receive correspondin pro- 3ections M, (Figs. 2 and 3) foi-med on the edges of perforated metal disks or platos D. The latter are some eightin number, and arranged horizontally and equidistantly, one above an other, as shown in Fig. 1. The holes in the series of disksD, are largest in the lowest one and smallest in the npper one, in other words, the diaineters of the holes gradually decrease from the bottom disks D, so that the flow of gas is retarded more and more and is hence more intimately mixed as it passes npward to the tip E.

Below disks D, in the bottom of the gas chamber, is a series of wire-gauze disks C- say ton or twelve in numberwhich are suy perposed and in close contact with eaoh other as Well as with the lining Gr. similar disks F', some five or six in number are arranged above the disks D, in the top of the gas chamher, as shown.

The aforesaid tip E, is madeof some metal which is a good conductor of beat and, being in contact with the shell or lining G, as shown, the latter as Well as the plates D, beoome heated by conductivity, to a comparatively high degree. The same is obviously true to a less extent of the ganze disks O and F. It is therefore apparent that the gas passing through the body of the burner to the point of combnstion (E) is not only intimately mixed so as to acqnire honiogeneity, but also beoomes heated to a degree but little below the point of combnstion, so that When it reaches the dame its Carbon particles are in condition to quickly incandesee and thns be perfectly consumed, so that a maxiinum degree of illurnination is obtained.

What I claim is- 1. In a gas burner, the combination, with a heat-oonduoting part G, having sockets as specified, of perforated disks D, arranged transversely and having projections adapted to enter said sockets, substantially as shown and described.

2. In a gas bnrner, the combination, with the hollow body and heat-conducting shell, or lining, therefor which is in contact with the body as shown, and provided with soekets as specified, of a series of snperposed but separated perforated disks having projeetions which enter said sockets, and a metal tip which is in contact with both the body and its lining, as shown and desorihed,

3. In a gas bnrner, the combination, with IOO nhe hollow body O, of an inne shell 01 beat-- conducting lining G, composed of longtudi nal sections which are fitted looscly together, and a metal tip is in contact with the upper extremties of the lning sections and body, as shown and described.

4. The mproved gas burner composed of the hollow body, the heat-conducting sectional lining having sockets and conforming to and lying n contact with the body as shown, a series of superposed but separated, pcrforatcd disks havng projections which enter said sockcts, series of wire-gauze disks superposed and arranged at bottom and top of the burner Chamber, and the metal tip which is in con- 5 tact with the body and luing as shown and descrbed.
